[HS] need help with 'learn shopping order' feature

Hello,

After some time living without a pda and thus unhappily living without Handyshopper I decided to make the switch back.  I was delighted to find the 'learn shopping order' feature - Terrific Idea!!!
I have found that I can only get it to work however on newly created databases - my existing ones don't work.  I believe I read that this has something to do with prior use of a desktop hs app?  (In my case that makes sense as I had used one at one point) At any rate I'd like to simplify the process of getting this all to work with this great feature.  Should I assume that my existing db's are completely incompatible or is there some way to transfer part of the info to a new db without compromise.  My main db has 1173 items in it so re-entry is definitely something I'd like to avoid if at all possible.

Thanks in advance for your help!
Rebecca
